Got an Expression Error while I was developing SAIL code.

Can you check the application server log for relevant entries at the time of this error. The "Caused by" in the stacktrace should have an indication as to what caused this.

Please send the sail code for understanding

If you could export the rule as a patch and share I would be happy to look into this.

Thanks for the replies!
Please find the attached patch. The SAIL rule name is OK_MMS_SAIL_createMeetingDetailsPage.
@Abhi: Please give me some time, I will find and attach the respective logs also unless it's not deleted.

Last question. What do you mean "while developing"? Were you testing the rule with values? Typing out the expression?

I was typing out an expression. Thanks!

What version of Appian? Also, are you reproducing this error often or was it one time?

7.10 version. I have not checked really whether it's reproducing or not. But, I have a copy of the sail code during which I got this error. PFA.
